Title: Gas laser oscillation
Inventor: NISHIDA NAOTO
IPC: H01S3/097
Filed: 1987-03-23
Abstract: PURPOSE:To oscillate pulse gas laser radiation efficiently, by supplying a main discharge current having a large current value across the discharge electrodes of a discharge tube immediately after a discontinuous discharge current having a small current value is supplied. CONSTITUTION:A DC high voltage is applied across discharge electrodes 2 and 3. Under the state a grid voltage Vg is applied to a triode 13, generation- command pulse signals are sequentially sent to a pulse-signal generating circuit 14 and a pulse generating circuit 15 from a delay circuit 16. Then pulse signals a1 and a2 are sent out. Then, an N-P-N type transistor Q1 is conducted at first. An auxiliary discharge current k1 flows between the discharge electrodes 2 and 3 of the discharge tube 1 by way of the triode 13. Then, an N-P-N transistor Q2 is conducted, and a main discharge current k2 flows. Thus main pulse discharge is generated in the discharge tube 1 by the supply of the main discharge current k2 immediately after the supply of the auxiliary discharge current k1, and oscillation of pulse gas laser radiation F is conducted.

The main body 36 of the metal fitting comes into contact with the web end edge of the bar material 1. The upper die 24 is then moved in the moving B direction and brought to the just above the lower die 21 and a vertically moving frame is descended as well. The upper die 24 is further descended with the engagement of the second rack 50 with the first rack 36, then it comes into contact with the upper face of the web of bar material 1. The center metal die 5 is moved in the direction A with the extension of the piston rod of main cylinder and the bar material 1 is bent with the back die 22 becoming the point of force. In this case a metal fitting 17 is not to be retreated with being defeated by the powerful load because of the press metal fitting 17 and upper die 16 being integrally connected via the racks 36, 50.

Title: Clamp tool for clamping workpiece
Inventor: RAINERU RENTSU
IPC: B23B31/117
Filed: 1990-03-20
Abstract: PURPOSE: To reduce the requirements for fitting accuracy by forming a tensile element with an alloy having a shape memory capability, and also providing to the alloy such an alloy composition that a reversible pseudoelastic or superelastic range capable of inducing a stress at a clamping tool service temperature is present. CONSTITUTION: A tensile element 7 is screwed onto a conical screw 11 of a pin 10, moved by a clamping nut 12 axially on the inclined thread surface of a screw 11, and subject to a force over the entire length and all around the screw by the action of a cone. The force in the direction perpendicular to a clamping surface 8 raises the element 7, and tightens a work piece 5 fixedly by an arbor 1. The element 7 is made of a shape memory alloy in which austenite is present at the service temperature of a clamping tool 1. Under this condition, an alloy composition is selected so that the alloy shows superelastic or presudoelastic characteristics. When the element 7 is extended in diameter and a load is removed from the element, it is returned again to the initial state rapidly.  Thus even a workpiece with a large tolerance can frictionally be clamped by large clamping force and with high concentric accuracy.
